Figure 1

STM image, 60 Å $times$ 60 Å, of Br on Cu(100).

Full size figure and legend (35K)

Figure 2

Image taken immediately after Fig. 1, showing the same atoms marked A,B,C and D.

Full size figure and legend (41K)

Figure 3

STM image, 120 Å $times$ 120 Å, showing most Br atoms moving across the clearly visible Cu lattice. (The image was taken at 2 nA, 10 mV.) Each individual hop is in a {110} direction.
